Title: Improvements in yarn and like winding-machines
IPC: B65H67/02
Filed: 1926-02-09
Abstract: 270,423. Marks, E. C. R., (Barber-Colman Co.). Feb. 9, 1926. Creel arrangements; skewers; thread-guides.- In machines for winding yarns &c. means are provided for withdrawing the support, such as a bobbin skewer, from an exhausted supply bobbin a, Fig. 7, inserting it in a reserve supply bobbin b and repositioning it so that the winding may be continued from the bobbin b. The invention is described as applied to a winding-machine provided with a mechanism I which travels along the machine and operates upon each winding unit, for example as described in Specification 156,607. A rack 88 is depressed, as by a cam bar J on the travelling mechanism, and rotates a shaft 34 which carries a crank pin with a cam portion 30, Fig. 13, so that the support 17 for the supply bobbin is moved longitudinally and pivotally as shown in Fig. 7. When the shaft 34 begins to rotate a central spindle 22, Fig. 13, is moved against the action of a spring 27 by the cam portion 30 and fingers 19 are withdrawn, thus freeing the bobbin, which, upon further withdrawal of the support, topples and falls through the open rear side of the compartment 4. During the completion of the rotation of the shaft 34 the support pivots on pins 37 and is entered into the reserve full bobbin h, and the fingers 19 are released and the bobbin b passed between spring-controlled gates 5 into the operative posttion. The rack 38 is moved away from the pinions on the shaft 34, when the pinions have nearly completed a revolution, by the engagement of a lug 46 on the shaft with a shoulder 48 on the rack, and continued movement of the rack engages fingers 50 with the pinions to prevent overrunning. Should the pinions overrun, the pressure of the teeth forces the rack against a stop 51. The rack is retracted by a spring 41, the teeth being withheld from the pinions by the contact of the lug 46 with a surface 47 on the rack, until the lug rides over the shoulder 49; rotation of tha pinions is prevented during this movement by a pawl 53. To prevent upward movement of the travelling mechanism out of its normal path if the rotation of the pinions is resisted by the jamming of a bobbin and the full descent of the rack, which in these circumstances jumps the pinions, is prevented by the consequent fouling of the fingers 50 and the pinions, a fixed guide bar 55 is provided to deflect the rack if the lug 46 does not operate to move it; normally, in such circumstances the rack 45 will jump into and out of engagement with the pinions. A thread guide is mounted in the top wall of the compartment 4 and comprises a member having an eye with a flared entrance 12, Fig. 9, and guard fingers 13, and a slot is formed in the top wall to permit the leading of the reserve thread to the guide.

Abstract: 825,963. Two-part couplings. DANN, F., BERGNER, C. F., and KABELWERK VOHWINKEL A.G. Feb. 7, 1957 [Feb. 8, 1956], No. 4214/57. Class 38 (1). A plug-and-socket coupling comprises identical halves each consisting of a cylindrical cablereceiving portion 1a with a semicylindrical, off-set and hollow extension 1b supporting a contactcarrying plate 3. The contacts comprise two rows of contact blades 3a and two rows of pins 3b arranged so that when the coupling halves are brought together in a direction perpendicular to the cable axes, each pair of pins embraces a pair of blades. In this position, the cable axes are aligned and the two halves are secured together by rotating a ring 11 on each half, each ring having a spiral groove 15 which receives a pin 25 on the other coupling half so that said rotation causes the coupling halves to be pressed together. Gaskets 9 seal the meeting faces which also have interfitting pegs and recesses 7, 8 to transmit the axial pull on the cables. Each cable 2 is secured in its respective coupling portion 1a by a hollow sleeve 16 which surrounds the stripped cable and is filled with soft solder or synthetic resin, said sleeve being retained in the portion 1a by a nut 19. A gasket 21 is compressed against nut 19 by a further nut 22. When disconnected, the coupling halves may be protected by covers, one of which is shown in dotted lines in Fig. 1. The cover has a body portion similar to the portion 1b and a platelike locking member 11b similar to one of the locking-rings 11. Fig. 10 shows a coupling half for mounting on a panel and adapted to receive a coupling half according to Fig. 1. In this case the portion 1a is replaced by a mounting foot 30a and a locking ring 11a similar to the locking member 11b on the cover is provided. An intermediate coupling for preserving the sequence of the connections where a number of cable lengths are connected together is shown in Fig. 11. Two coupling halves 32, each similar to the one shown in Fig. 1, are coupled together by a sleeve 33 and their contacts interconnected by a short length of cable.

Title: Improvements in and relating to gas calorimeters
IPC: G01N25/42
Filed: 1920-02-11
Abstract: 162,826. Fairweather, J. H. Feb. 11, 1920. Calorimeters.- Consists of an apparatus for supplying water to gas calorimeters, in wluch the rate of flow of water to the calorimeter is automatically corrected for atmospheric temperature and pressure, so that in calculating the calorific value of the gas no account has to be taken of the tabular number of the gas. In the form shown in Fig. 1, a vessel 1 contains a closed airtight vessel 2 having at about its centre an oil chamber 3 formed by a partition 4; a pipe 5 connects the two parts of the vessel 2. The chamber 3 communicates by a pipe 6 with a float chamber 7 containing a float 15 within a vessel 8. The vessel 2 has an extension 9 to which water is supplied by a pipe b. A portion of the water overflows from the extension 9, passes over the vessel 2, and escapes from a suitable drain. The remainder of the water passes along a pipe 10 into a vessel 11, through the base of which passes a pipe 12 dipping into a vessel 13 carried on a rod 14 secured to the float 15. The water overflowing from the vessel 13 enters the vessel 8 and passes to the calorimeter through an outlet 16. The float chamber is protected by a cover 17 and communicates with the atmosphere. The position of the float and consequently the effective head of water depend on the atmospheric temperature and pressure, the shape of the chamber 7 being such that the desired correction is obtained. In a modification, the long outer vessel 1 is dispensed with and the air vessel and oil chamber are at a lower level than the float chamber, air being in this case supplied to the vessel 2 under pressure. In the modification shown in Fig. 3, the oil chamber and the float and float chamber are dispensed with. The air vessel 28 communicates by a pipe 30 with the interior of an inverted bell 31 floating in water in a. fixed vessel 32. Secured to the bell 31 is a support 33 carrying a vessel 34 into which passes a pipe 35 from the water-supply vessel 36. The water overflowing from the vessel 34 passes along a pipe 40 to the calorimeter. The bell &c. are balanced by weights 41, 43 secured to cords which pass over a pulley 42 and a cam 44 respectively. The varying movement of the weight 43 corrects for the variations in buoyancy of the bell as it rises and falls. The vessel 28 is enclosed in a vessel 29 which is supplied with water by a pipe 37.

Title: Improvements relating to basic phthalonitrile derivatives or their halogen hydracid salts, and their use
IPC: C07D209/44
Filed: 1953-02-16
Abstract: Phthalocyanines are formed in substance or on the fibre by reacting a copper or nickel salt with the product obtained by treating phthalonitriles with hydrogen halide, followed by ammonia and optionally liberating the base formed from its hydrogen halide salt (see Group IV (b)).  The reactants may be incorporated into printing pastes with the usual additives, and printed on to cotton, linen or regenerated cellulose, usually in the form of fabric, followed by steaming.  In examples, products obtainable by the action of hydrogen bromide on phthalonitrile and its 4-chloro- and 4-nitro-derivatives, followed by treatment with aqueous or alcoholic ammonia, react with copper or nickel salts to give blue or green dyes, with or without incorporating into pastes with glycols, alkanolamines and other additives, and may be printed on to cotton to give blue or green dyeings.ALSO:The invention comprises halogen hydride salts of basic phthalonitrile derivatives obtained by treating phthalonitrile with aqueous hydrogen halide to form an addition product, followed by treating this with aqueous ammonia or agents producing the same, to give a basic nitrogen compound as salt, from which the base can be liberated by means of alkali.  Nuclear substitution products of phthalonitrile may also be used.  The salt products form phthalocyanine-copper and nickel complexes readily and also when previously liberated as the bases.  The new basic derivatives decompose into imino-phthalimidines and ammonia, on heating, give neutral salts with mineral acids and decompose when heated in aqueous acid.  They can be incorporated into textile printing pastes with the addition of alkanolamines and copper or nickel salts, which when printed on material produces good prints.  In examples, phthalonitrile, 4-nitrophthalonitrile, and 4-chlorophthalonitrile are treated first with hydrogen bromide and then with aqueous or alcoholic ammonia to give yellowish products as hydrobromide salts, from which the basic substances are liberated, and may be used to produce fast blue dyes with copper salts in a solvent, or nickel salts in aqueous solution, which may be printed on to cotton either before or after their formation. The hydrobromide salt of the unsubstituted product obtained after reacting with ammonia as described, has the empirical formula C16H19O2N6Br; the base free from hydrogen halide, is described as an amine of possible empirical formula C8H7N3.

Title: Improvements in or relating to processes for preparing phthalic acids by oxidation of dialkyl benzenes
IPC: C07C51/265
Filed: 1955-02-14
Abstract: In the preparation of terephthalic acid, isophthalic acid or phthalic acid by oxidation of a dialkylbenzene by means of oxygen or an oxygen-containing gas in a liquid medium in which the resulting phthalic acid is insoluble or is only so slightly soluble that it precipitates therefrom in a solid form, the solid phthalic acid product so obtained is separated from the reaction liquid and purified by washing with an organic solvent and also with water.  The liquid medium for the oxidation may comprise an excess of the dialkyl benzene to be oxidised or a liquid in which the dialkylbenzene is soluble such as an organic acid.  Catalysts of one or more compounds of metals of variable valency may be used.  Organic solvents mentioned are acetone or the same organic acid that is used as the liquid medium.  In an embodiment of the invention, terephthalic acid produced by the oxidation of a p-dialkylbenzene using a liquid medium of an organic acid is washed with fresh organic acid, the solvent adhering to the product is removed by evaporation or water washing and the product is then washed once with hot or cold water at ordinary pressure.  The organic acid washings may be recycled to the oxidation reaction.  When washing terephthalic acid prepared by oxidation of p-diisopropylbenzene cold organic acid is used, but if the terephthalic acid is prepared from p-xylene hot organic acid is used.  In an example, p-diisopropylbenzene in acetic acid is oxidized by air as described in Specification 737,439 and the crude terephthalic acid is washed at 20 DEG  C. with acetic acid and then water; comparative treatments by washing with acetic acid or water alone are illustrated.
